Title: Thrust engine by levitating rotation
Inventor: YAMADA TADANORI
IPC: F03G7/10
Filed: 1992-06-03
Abstract: PURPOSE:To generate a thrust by a method wherein a weight to repeat linear acceleration speed movement is rotated around the center of repetition on a rotary shaft, extending at right angles with the direction of the linear acceleration movement, and at the same period of a repetition period to generate and hold levitating rotation. CONSTITUTION:A spring A15 is arranged between a rotary cylinder 4 and a rotary weight 5 and a spring B16 is arranged on the opposite side thereto. In a state that the spring A is contracted, the spring B is brought into an expansion state. Both the springs are the same as each other. In a case of a spring, not only a repulsion force but also a contraction force produces a thrust. Movement of gravity owing to expansion and contraction increases a thrust by an amount equivalent to the movement. The number of the springs and the force of the spring are set to an arbitrary value provided an upper and a lower and a right and a left one are same as each other. A method to regulate a thrust includes a method wherein a thrust is regulated by regulating the output of a motor to rotate a drive shaft and a method wherein the regulation is effected by offsetting a thrust in a way that the same devices make a pair and are positioned facing each other in a state that a thrust left generated.

Title: Bonding wire and semiconductor device and bonding method using it
Inventor: SASAKI KEIJI
IPC: H01L21/60
Filed: 1992-07-15
Abstract: PURPOSE:To enable a bonding wire to return to its original shape without performing any rehammering work even when the wire is deformed by using a shape memory alloy as the material of the bonding wire. CONSTITUTION:A shape memory alloy is used as the material of a bonding wire 1 which electrically connects the pad of a semiconductor chip 4 to a conductor pattern 3 around the pad. For example, a metallized pattern 3 formed on a base 2 is connected to a semiconductor pellet 4 mounted on the base 2 through such a bonding wire 1 made of the shape memory alloy. After bonding, the wire 1 is made to memorize its shape in a normal state in a heating atmosphere before the chip 4 is carried to the next process. Therefore, even when the wire 1 is deformed due to an external force, the wire 1 can return to its original shape when the wire 1 is heated again.

Filed: 1988-07-27
Abstract: PURPOSE: To improve the bending quality of a pipe by forming in a groove of a bending die a bottom surface part having a radius smaller than that of a desired pipe and a groove shape having the radius larger than that of the pipe.

Filed: 1987-07-30
Abstract: PURPOSE:To provide an optical recording card which is not degraded in recording sensitivity using a recording principle except the evaporation and deformation of a recording film by laminating a light transparent sheet, ferroelectric layer which is changed in optical characteristics in the oriented and non-oriented states of molecules and the electrode in contact therewith. CONSTITUTION:A thin metallic film 2 is formed by vapor deposition of an underlying metal for the electrode or coating of an org. metal on a supporting substrate 1 in order to attain the oriented initial state. A film 3 of the ferroelectric layer is then formed by sputtering on the thin metallic film 2 and an electrode plate 4 having the surface polished to a specular surface is brought into contact as the electrode facing the underlying electrode with the surface of such laminated body and is initially oriented to form a transparent film. After the transparent sheet 5 is adhered onto the initialized ferroelectric layer 3, the substrate is cut to the size of a card and the optical recording is thus obtd. Laser light is projected to this optical recording card to disturb the orientation by a local heating and to convert the disturbed part to a non- transparent part, by which information is written and recording is executed.

Title: Communication procedure discrimination method
Inventor: SANO MASAHIKO
IPC: H04L29/06
Filed: 1991-07-02
Abstract: PURPOSE:To allow a controller to be set automatically so that a communication procedure of an on-line terminal system is the same as a communication procedure of a data communication network by discriminating the communication procedure of the data communication network. CONSTITUTION:An on-line terminal power supply controller 3 outputs a discrimination signal used to discriminate whether or not a data communication network uses, e.g. a packet mode communication procedure to a host computer being a heart of a data communication network via a MODEM 1. When a reply to the discrimination signal is sent to the on-line terminal power supply controller 3 from the host computer, the on-line terminal power supply controller 3 discriminates it that the data communication network uses the packet mode communication protocol. On the other hand, when no reply comes, the on-line terminal power supply controller 3 discriminates it that the data communication network uses, e.g. a private line communication protocol. Then the on-line terminal power supply controller 3 sets automatically the communication protocol of the on-line terminal system so as to be in matching with the communication protocol of the data communication network.
